Introduction

Congratulations on your purchase of a Digital Subscriber Line (DSL)
modem. The DSL Modem is part of a system that provides an
integrated end-to-end solution for data connectivity, multimedia
services, and high-speed Internet access services using an
asymmetrical digital subscriber line (ADSL) transmission over your
current telephone wiring. With ADSL technology, information can be
processed at speeds up to 250 times faster than today's analog
modems.

1.1 ADSL Technology

As the interest in telecommuting and the Internet grows, the search
for methods of delivering larger amounts of data over the existing
copper telephone wire increases. ADSL technology is one method of
delivery.
ADSL technology uses advanced digital modulation to transmit data
at high speeds over standard telephone wiring. This technology can
download data at 8 Mbps and upload data at up to 768 kb/s.
The DSL Modem is part of a system that enables Internet service
providers and local telephone companies to offer high-speed Internet
access, virtual private networks (VPNs), telecommuting, video on
demand, and other broadband services.
